Status: No Feedback
Bug Type: ODBC related
Operating System: Windows XP
PHP Version: 5.0.0
New Comment:
I'm encountering this same issue using NexusDB and the ODBC driver in
PHP 5.2.0.
* The columns returned by odbc_fetch_array() are not indexed by their
column names, but by the values.
For Example:
"select Code, Designation FROM C_ARTICLE", I get:
Array
(
[120105003] => 120105003
[CacheCoeur TS] => CacheCoeur TS
)
* "SELECT * ...." crashes the (Apache 2.0.59) webserver.
"Parent: child process exited with status 3221225477 -- Restarting."
from Apache logs)
However, I can use odbc_fetch_array() multiple times which OP was
unable to do.
I tried using PDO and get the following for any query:
Warning: PDO::query() [function.PDO-query]: SQLSTATE[HYC96]: <<Unknown
error>>: -1 Access violation at address 0589B12F in module
'nxOdbcDriverV2.dll'. Write of address 00000000 (SQLDescribeCol[-1] at
ext\pdo_odbc\odbc_stmt.c:394)

I know this is side-stepping the issue slightly, but would you mind
testing the PDO?
For a bit more info:

You'll need:

Please reply directly to me ([EMAIL PROTECTED]) with feedback on PDO.

Description:
------------
Accessing a NexusDB database from PHP using the ODBC driver results in
two problems, that cannot be reproduced using any other ODBC query
tools:
(1) The columns returned by odbc_fetch_array() are not indexed by their
column names, but by the values!!!
(2) Getting one row with odbc_fetch_array() is fine, but as soon as you
ask for the second one, the web server complains about an access
violation (both Apache and IIS).
Apparently the driver does something that the ODBC library in PHP
doesn't expect, but most other windows programs think is fine.
The problem exists in PHP 4.3.7 as well as PHP 5.0.0.
Reproduce code:
---------------
$db = odbc_connect("nexusdb", "", "");
// Don't use "select *", it will crash immediately.
// This is something the other ODBC tools seem to
// know and deal with as well.
//
$result = odbc_exec($db, "SELECT id, name FROM table");
$num_records_fetched = 0;
$num_records_to_fetch = 2;
while ($row = odbc_fetch_array($result)) {
$num_records_fetched++;
echo "Row {$num_records_fetched}:";
foreach ($row as $key => $value) {
echo " {$key} => {$value}";
}
if ($num_records_fetched >= $num_records_to_fetch) {
break;
}
}
Expected result:
----------------
I'd expect to see:
row 1: id => 0001 name => foo
row 2: id => 0002 name => bar
Actual result:
--------------
I get an "access violation".
If I change "num_records_to_fetch" to 1, it no longer violates access,
but I see this instead:
row 1: 0001 => 0001 foo => foo
